It is narrated from Sayyiduna Abu Malik Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to maintain equality in recitation and standing in all four rak'ahs, except that he would make the first rak'ah a little longer so that more people could join in that rak'ah. He would make the men stand in front of the children, the children behind them, and the women behind the children. And when he performed sajdah and when he rose from sajdah, he would say Allahu Akbar, and when he sat after two rak'ahs and then stood up, he would again say Allahu Akbar.
